Rheometer: MCR 72 and MCR 92

Key Features Rheometer MCR 72 and MCR 92

---

Two models designed for your application

Two new rheometers are available: MCR 72 is equipped with a ball-bearing motor (very robust in use, no compressed air required) and MCR 92 with an air-bearing motor (highly accurate for sensitive samples). Both rheometers enable measurements in both rotational and oscillatory mode. The choice of rheometer depends on your application. To investigate the deformation and flow behavior of your sample (also at different temperatures) consider MCR 72. For observing your samples’ structure, MCR 92 is recommended. Both instruments have a motor which lifts up the measuring head automatically to set an exact measuring gap. This gap is 100 % reproducible. MCR 72 and MCR 92 can both be equipped with temperature devices to cover a range from -40 °C up to 400 °C.

Your key to accuracy – the motor technology

25 years of experience in one motor – you only get this with rheometers from Anton Paar. The air-bearing-supported synchronous EC motor deploys a frictionless synchronous movement of the rotor inside that enables the most sensitive and therefore most precise movements. Whether investigating solids or low-viscosity liquids your results are accurate across a wide viscosity range.

Step-by-step software

The intuitive RheoCompass™ software helps you to find the test template you need, customize tests and analysis definitions, export your data and generate reports. You are guided through your first rheological measurements with predesigned but individually adaptable templates, including integrated videos and pictures for extra support. Different accounts can be created for each operator working in the lab.

Unique features for easy handling and reproducible results

The literal highlight of these two rheometer models is clearly TruRay, the lighting of the measuring surface that can be gradually regulated for a clear view of your sample. When changing between measuring systems, QuickConnect allows one-hand connection of the measuring systems and ensures fast, convenient system changes without the use of a screwing mechanism. After this, Toolmaster™ takes over by automatically recognizing the mounted tool and temperature units. Finally the SafeGap feature ensures that the setting of the measuring gap is always identical for every measurement and exactly reproducible every time.

Experienced experts close to you

Anton Paar’s worldwide service network ensures that an expert on your system is always close by. One thousand installed instruments around the globe, an extensive application database, a website full of practical information (World of Rheology), the book “Applied Rheology – With Joe Flow on Rheology Road”, eLearning courses and numerous published works by our rheology experts confirm that Anton Paar is the first choice for answering any rheological question you may have.

– MCR 72 or MCR 92 plus accessories with a special academic discount

– Free EDU Toolbox including lab equipment and educational material

1) Depending on sample properties

2) Depending on measuring point duration and sampling time, practically any value is achieved

3) Set frequencies below 10-4 rad/s are of no practical relevance due to the measuring point duration > 1 day

4) System temperature, sample temperature may vary. For measurements at very high or low temperatures a calibration in the sample gap is recommended.
